Application filed December 28,1903. Serial No. IiifgA To all whom itindy concern:

Be it known that I, ARTHUR S. Cowan, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented an Improvement in Looms, of which thefollowing description, in connection with the accompanyin letters andgures on the drawings representing-like parts.

This invention has for its object the production of a novel loom forweaving fabrics in which short or separate lengths of vweft are laid insheds formed in Warp-threads, the loom herein to be described alsohaving the capacity of inserting into sheds in the Warp following thosein which the short wefts are inserted a weft taken from a cop or bobbin`I and hereinafter designated as a continu-i ous" weft ascontradistinguished from a short weft. The short wefts will preferabl Ybe of hair or some such material that will give stiffness to the fabricbetween its selvages and will aid in maintaining the vvar s separated asdetermined by the Weave of t e fabric, it being understood that thewarps may be manipulated by shed-forming mechanism in the formation ofthe sheds as they are commonly manipulated in Weaving plain or twillcloth or in Weaving leno or cross or any fancy Weavin The manipulationof the warps depen s on the shed -forming mechanism, and in connectionwith my invention, to be hereinafter more fully described, I may use anyknown form of shedforming mechanism, that depending on the weave orcharacter of the cloth to be woven.

Prior to this-invention hair-wefts in short lengths have commonly beenengaged at their leading ends and drawn into the shed by means o nippersmoving transversel r of the warps and traversing the shed, the s iortWefts of hair or whatever material being taken one at a time from abiinch at the loom end. I have devised an entirely new system and meanswhereby fabrics containing short wefts in whole or part ma be woven,and, if desired, a continuous we t may be inserted at intervals in anysheds omitting the short wcfts.

In accordance with my invention I employ a shuttle for carrying aplurality of Wefts which are selected singly by suitable shortdrawings,is a specification, like weft-selecting means, each selected weft beinengaged by a weft-holder. The wefthoIder after taking the selected weftfrom the selecting means is moved toward and is stopped outside oneselvage, While the shuttle carrying the remaining portion of theselected weft is moved through the shed into the opposite box, theshuttle in traversing the shed paying out the selected weft, a part ofwhich is yet engaged by the weft-holder, the said shuttle leaving theshort weft in the shed to be beat into the fell in usual manner.Further, besides employing a shuttle as the means for holding aplurality of short wefts and for layin said short wefts in the shed bymoving the s uttle across the warps I have provided means whereby saidshuttle is carried in a shuttle-box, so that the short-weftcarryingshuttle-boL-With its shuttle, may be put into operative or ino erativeposition with relation to the race o the lay, as it is desired that saidshuttle shall be operated to lay a short weft or its operation besuspended for any desired number of picks, that depending on usualshuttle-box pattern mechanism. The shuttle-box illustrated has a cell(shown as located below the shuttle-box cell) for controlling theshort-weft-oontaining shuttle, and when the cell of the shuttleboXcontaining the short weft containing shuttle is in its inoperativeposition the other cell of the shuttle-box containing a shuttle forsupplying a so-called continuous weft occupies lts operative positionwith relation to the race of the lay. The shuttle-box cell containin theshuttle carrying and presenting the slgiort wefts has coacting therewithweft-selecting means to be described. It will be understood that theloom may have like shuttle-boxes and weft-selecting moans at itsopposite ends. The short wefts aro usually of a length a little inexcess of the Width from selvage to selvage of the fabric to be Woven,and, as will be understood7 one end of the short weft is held outsideone selva e while the shuttle containing the short vieIt is being movedthrough the shed, the leading end of the short weft in the shuttle beingdelivered therefrom substantially as the shuttle enters the oppositebox, and to prevent any accidental curling or undue bending of the shortweft that might result in the formation of loops therein when the iOOselecting means and operating devices therel through gears,

reed meets the short weft to beat it into the fell l have provided whatI shall hereinafter designate as sliort-weft-controlling" means, saidmeans, as herein illustrated, being more or less in number of the war-threads It is custonnri'y in looms or'weaving pei'- feet goods toprovide devices acting to control the stopping ol the loom automaticallywhenever the weft is exhausted oi' broken, aiid one part of the loombeing stopped all parts are stopped. In the nove loom herein to bedescribed, wherein short wel'ts are used, the absence of a short wefteliects only the immediate stopping, throu rli the feeler cooperatingwith the lay, of Viut a part of the loom viz., the pattern mechanism forcontrolling both the shed-forming and the shuttle-boX-movirigii'ieclianisms-and at this time the knives and hooked jacks of thesliedforming mechanism may move andl continue to hold open the sameshed, the short-weftselecting means and the means Jfor moving theshort-weft-carrying shuttle continuing to run after saidpattern-surfaces have been stopped, so that said weft-selecting means,in case a short weft should iiot be selected when the nippers were firstclosed, will continue to operate throughout the time allotted thereforin the cycle of operations of the loom, and if the sliort-weft-selectingmeans selects a short weft in the allotted time said patternsurfaceswill iiinnediatel),7 start again automatically, and the short weft willenter the then o en shed-the saine shed that said weft s iould haveentered if the selecting means had operated in its proper time. Shouldthe continuous weft be exhausted or broken, the action of the mechanismwill be suspended in like manner until the continuous weft has beensupplied in usual manner, and at suoli time the entire loom may bestopped in any usual manner by disconnecting the shaft of the loom, thatis driven by power, either the crank-shaft or the camshaft, from itsprimary moving means.

Fi ure 1 is an elevation looking at the front of a oom at the left-handend thereof, said loom containin some of the features of my invention,the s Little-box rod, part of its actuating-chain, and means for movingthe picker-stick Ba being omitted to avoid coinlication of the drawing.Fig. 2 is a leftand end elevation of the loom shown in Fig.

Fig. 3 is a partial section of the loom Fig. 1, together with part ofthe shown in means for moving the shed-forming inechanism andpattern-cylinder and the feeler of the weft stop-motion and part of thetake-up. Fig. 4 is an enlarged view of part of the apparatus shown inFig. 1, the outer uides for the shuttle-boxes, the standard 4, and theguide-rod for the weft-holder being broken out, the weft-holder-openingmeans being omitted, said figure showing the short-weftlor more indetail on a larger scale, the weftliolder bein,r shown as engaging ashort weft. Fig. 5 is a pian view of the parts shown in Fig. 4 directlybelow it lookin at Fig. 4 in the direction of the arrow (l, ut with theparts iii the position Fig. 1. Fig. 6 is a plan view of the parts ofFig. 4 directly below it, said figure showing the weftholder having beenstarted oii its return stroke. Fig. 6a is a detail showing theweft-holder in its position for holding the short weft near the selvagewhile the short-weft shuttle completes its movement, this figure showingthe parts of Fi 6 iii the position occupied by them just beore theweft-holder starts on its return stroke. Fi 7 shows in elevation theselecting means o Fig. 4, the weft-holder bein in a position to engageand hold the short we t selected from the mass carried by the shuttleand next to be laid in the shed. Fig. 8 shows part of theshort-weft-selecting means illustrated in Fig. 7, the nippers of theselecting means being shown as having entered the shuttle preparatory tograsping the short weft and as being held open, the shaft DT beingrotated, it will be supposed. Fig. 9 is a plan view of a shuttle withoutthe short wefts. Fig. 1() is a section in the line zr, Fi f. 9, showingthe shuttle with a plurality of s ort wefts laid therein. Fig. 11 is asection of the loom lfrom front to rear, chiefly to show one form ofshort-weft-coiitrolling means, the means illustrated being adapted toact through the warps that they may act frictionally on the short weftas the latter is laid in the shed. Fig. 12 is a view looking at Fig. 11in the direction ofthe arrow 3. Fi 13isa detail showing one form ofshed-forming mechanism that may be used. Fig. 14 is a detail of theshed-forming pattern-surface and means for rotating the same. Figs. 15and 16 are details in plan view of the lever moved by the weftstop-motion, showing the clutch, to be described, closed and open. Fig.17 shows part of the loom represented in Fig. 1 with the shuttle-boxrod, part of its actuatin -chain, and pickeractuating mechanism. ig. 18is a left-hand side elevation of thc parts shown in Fig. 17.

Referring to the drawings, A represents part of' a loom-frame havingerected upon it a stand A for supporting the arches of the loom,portions of said stand also supporting the head A2, (see Fig. 13,) inwhich is moved the usual knife-bars 14 14, actuated bv an elbow-leverA5, common to any do byhead-as, for instance, in United States PatentNo. 388,318, dated August 21, 1888. The loom-frame has a crank-shaft A6,that may be driven in any usual manner, the cranks of which are embracedby connectingrods A7, connected with the lay A", pivoted at its lowerend in usual manner and having a reed A". The loom-frame also has acamshaft A10, that is driven from the crank-shaft (shown by dottedlines, Fig.

2,) the cam-shaft revolving once while the crank-shaft revolves twice.Part of the warp Vze w', taken from the Warp-beam B, is led over aWhip-roll B' and a roller B2, and thence in any usual manner, accordingto the Weave of the fabric, through the harnesses, as represented inFig. 11, thence between the dents of the reed and over the roll B, sustained in front of the breast-beam B4, the fablric being led thence toany usual4 take-up rol The parts so far referred to by letter are andmay be common to usual power-looms. The lay has usual guideways tosustain the ends 2 of a shuttle-box B5, containing1 two cells, one abovethe other. The upper cell contains the novel shuttle B, herein to bedescribed and best illustrated in Figs. 9 and 1G, said shuttle carr inga plurality of short wefts e, arrange in a bunch, the shuttle shown inFig. 9 and representing my invention in one goed form having ashort-weft-receiving space in which may be laid the bunch of shortwefts, the Wefts being folded backwardly, one end of the bunch being cuteven and substantially abutting, as shown, a partition o of the shuttle.The shuttle has a short-weft-tension device e3, (shown as a leverpivoted at 112,) the short arm of which is acted u on by a spring all,said spring serving to pro( uce pressure upon the short Waits, forcingthe same with a gentle pressure against the abutment a5. This lever a?also yields somewhat as the nippel-s of the shortweft-selecting means tobe described are closed to grasp a short weft. The cell of the undermostshuttleebox of the pair, as herein shown, is adapted to receive ashuttle B7, (sce Fi 7,) that may be supplied with a cop or bo bincontaining Wound filling, said shuttle presenting the continuous fillingherein referred to.

Figs. 17 and 18 show the shuttle-boxes B6, the box-rod BG", the springB, and the chain B52, extended over sheaves B72 and B73, said partsconstituting a portion of usual means for shifting the shuttleboxes onthe lay that either the shuttle containing the short weft or theshuttlecontainingr the continuous weft may be placed at the level of the raceof the lay to be moved through a shed in the warps. Further illustrationof such mechanism would only tend to complicate the drawings, and itwill be understood that I may employ any usual drop-bex-shiftingmechanism common to Crompton or Knowles or other looms, the position ofthe shuttle-boxes beingP controlled automatically by a moving chain B,common to the loom referred to, the time of movement of said chain beingdetermined by indication carried by the usual shuttle-box means and notnecessary to be herein illustrated.

The shuttle B, containingr the short wefts, and the shuttle B7,containing the continuous weft, Will be moved through the shed fromeither salvage or end of the loom and from the cell of the shuttle-boxcontaining the same, whichever shuttle occupies its operative positionat the level of the race of the lay by picker-sticks B", (one onlyshown,) that may he moved in any usual manner common to looms. Figs. 17and 18 show one common form of devices for moving the picker-stick, and,referring to said figures, B64 shows a strap connected with an arm B65of a pickeractuating shaft B, sustained in bearings at the loom side andhaving a shoe B", that is struck by the roller B, carried by an arm B5,fast on the shaft All. The piclrerfstick, Fig. l., will cause theshuttle to traverse the warps and enter the usual box (not shown) at theopposite end ofthe loom-frame. The shuttle-box referred to has twostands B B, that sustain a guide B, (shown as a rod, see Figs. 1, 4, 5,and 6,) the guide being broken out partially in Fig. 4. This guidereceives loosely upon it a carrier C, having a depending slotted arm Cand a projection C2', (see Figs. 5, 6, and 7,) overlapping a portion ofthe shuttle-box, said projection sustaining the weft-holder, comprisinga stationary jaw al and a movable jaw al, having a irojection a8, thatabuts the short weft held y the seF lecting means, said movable jawbeing pivoted at of on the fixed jaw, the other end of said movable jawhaving a cam projection ax. The movable jaw is acted upon by a spring(1,1, that normally serves to close the jaws that they may grasp aselected short weft e, as represented in Fig. 4, said weft having beenselected from a mass of short wefts bynippers forming part ofshort-weft-selecting means to be described and held in the path ofmovement of the jaws of the weft-holder. The slide C has a dependingportion C', slotted as represented in Fig. 4. to be entered b v a studC3 of a lever C, pivoted at its lower end on a stud Cx. There is a slideand alever C ateach end of the leoni, and that said levers may heactuated to move said slides and weft-l'ioldcrs l have provided thecam-shaft Af of the loom with a scroll-cam C5, the edge of which is madeto travel between rollers @revoluble about studs erected on a plate bx,that may tip on an arm ti of a lever, the hub of-which is erected on astud b2, rising from a stand b3, connected with a suitable brace b4. Thearm b5 of the lever b has a stud lix, that receives the hubs of two likeeonnectinff-rods b 5" of different lengths, each'one, however, connectedto a lever C4. As the scroll-cam is revolved once for each two motionsof the crank-shaft, it will be noticed that, viewing,r Fig. 1, the slideC will be moved during a portion of the revolution of the shaft Am andwill then remain at rest for a portion of the revolution of said shaftand will then be returned to its starting point, Fig. 1. The weft holdermay be opened sooner or later in the movement thereof in the directionolI the arrow 4, Fig. 5, by adjusting a welt-holder opener a, shown as alever pivoted at a and made adjustable. through an adjusting devicc a,shown as a screw held in a projection ail lroln the shuttle-box, theprojection a K of the movable jaw f1.7 contacting with said weft-holderopener as the slide (l is moved to the right from the position Figs. l.and 5. The weft-holder when the slide C2 occupies its outward position(see Figs. 1 and 5) stands at a short distance to one side of theposition ol the short-we'ft-selecting means, to be described, that is toselect and hold a short weft to be presented to said weft -holder. Thenthe slide (T2 is moved, as will be described, the projection (l,X of themovable aw of the weft-holder in the n'iovement of the latter contactswith the first weft-hold er opener (L12 ljust as the jaws of theweft-holder arrive at the point where the weft-selecting means holds ashort weft a, (see Fie. 4,) that is to be given. up to the weftho der.The shuttle-box at its inner end sustains weft-holder-relcasiiig means.(Shown best in Figs. G and f3 and at the right in. Fig. 4.) rlheweft-holder-releasing means acts to open the weft-holder just as thelatter starts to move outwardly from the position occupied by it, Fig.6d, while the short-weft-carrying shuttle traverses a shed, and, asherein illustrated, said means comprises, essentially, a bracket (15,connected with the shuttle-box or stand B10 and the mouth BM of theshuttle-box, said bracket having a stud-screw al, upon which is pivotedan arm all, the outer end of which is shown as somewhat upturned (seeFig. 4) and ollset (see Figs. 6 and 6) with relation to the part of thearm designated aux, the extremityv of the upturned portion of the armCLU being somewhat rounded, as represented. The arm has a tail c, thatis acted upon by a spring al", secured to the bracket a, said springserving normally to keep the free end of said arm lifted, as shown inFie. 4, in line with the rounded proj ection cli oi? the movable jaw a7.When the weft-holder is moved inwardly from the position Fig. 4 to theposition Fig. 6a, the projection ax passes over and de resses the innerfree end of the arm a", an( the jaw is not opened. rlhe weft-holderopener having acted and the weft-holder having grasped a short weft, theweft-holder will be closed immediately by the spring al and holding theshort weft will continue its movement into the position Fig. 6, when thefurther movement of the slide will be stopped, and the weft-holder willhold the short weft at a short distance from the selvage of the fabricbeing woven. During the movement of the weftholder into this positionthe projection a* met the inclined upper edge of the arm a,1T anddepressed said arm7 the spring al" yielding, and said holder was notopened. The weft-holder is stopped with the projection ax olE themovable aw a7 almost or substantially touching the rounded portion c4Mof the arm ai". (See Fig. (iu.) During the movement of the weit-holder,as described, the shuttle B, provided with a series of short wefts, hasbeen or is being moved by the picker-stick referred to across the warpsto its opposite b oX, and the selected weft, one portion of which isheld by the weft-holder and the other portion of which is yet within thecontrol of the shuttle, is paid out or trailed behind the shuttle as thelatter crosses the warps and is deposited on the warps in the lowerplane of the shed, said shuttle Giving up fully the short weft about asthe shuttle enters the opposite box. The particular point at which theshort-weft shuttle shall give ulp the short weft is not, however, ofessentia importance so long as said shuttle carries the portion of theshort weft retained. by it, which weft has been selected and is held bythe weft-holder and lays said weft across the warps of the shed. Theshort weft having been laid in the shed, the weftholder must be openedto release the short weft. This is done immediately as the weftholder isstarted backwardly from its position Fig. 6 into the position Fig. (j,the weft at this time being held by the closing shed. The wett-holder isstarted toward the left from the position Fig. 6", and the projection afof the movable jaw contacts with the weftholder-releasing means. As theshort weftholder is moved into the position Fig. 6 the projection ameets the rounded upheld end of t 1e arm a, said arm at this time,however, not yielding, and consequently the aw a7 is opened to releasethe short weft then laid and to be left in the fabric. It will heunderstood that the weft-holder will grasp the short weft while yet heldby the selecting means outside the shuttle, and while said weft is soheld the shuttle B" and the weftholder will be started in their movementtoward the right, viewing Fig. 4, the weftholder being stopped next theselvage-warps and holding onto the short weft while the short-weftshuttle continues through the warp and delivers the selected short weftinto the shed. It will also be understood that a portion of eachshort-weft length will be left protruding beyond the sclvage-warps atboth sides of the fabric.

Heft-Selecting means-As shown best in Figs. 1, 2, 4, 7, and 8, theshuttle-box has erected upon it a stand D of suitable shape to sustainshort-weft-selecting means, said means, as herein shown, comprising ashaft D7, sustained in suitable bearings of said stand, the stand havingat its front end a head D12 The shaft D7 has fixed upon it anipper-opener cam D, a sto -cam b21, and a belt-pulley E. As the sha trises and falls with the shuttle-box the shaft D7 is shown as beingdriven from a belt E, surrounding the IIO `by a screw b.

ulley E thereon and deriving its movement rom a pulley E, carried by ashaft E3, hav ing its bearings in an upright E", connected with andrising from that portion of the lay having the usual guideway in whichthe shuttle-boxes are moved up and down. The shaft El* has a secondpulley El, that receives a belt E5, surrounding a driving-pulley E",fast on a shaft El, sustained in suitable bearings 3() 31 of the loomend. The shaft El derives its movement from a bevel-pinion E8, fast onthe end ofthe crank-shaft, through a bevel-pinion 17 on an upright shaft18 and bevel-pinions 33 and 34, said shaft E7 being driven continuouslyas long as the crankshaft is rotatedv A crank-pin of the disk DB entersa cam-groove in a block D, fast upon a rod D1, having suitable bearingsin the head Di2 and carrying at its lower end the nippers of theshort-weftselecting means. These nippers, as herein represented,comprise a member D', connected by a screw al* with an enlargement atthe lower end of said rod and a movable lever D, free to be turned abouta stud D3, carried by the member D of the nipper. A spring 1() actsnormally to elose the nippers onto the short welt when the nippers arelowered in contact with the bunch of short wefts presented by theshuttle BB. The nippers have to be opened when they a preach the bunchof short wefts in order t lat they may grasp a short weft, and to dothis l have provided a nipper-opener (shown as a lever D4) pivoted atD5, said pivot being surrounded by a suitable spring 20", that normallyacts to keep the short arm of said flipper-opener in contact with thenipper-oponin cam DE. The stop-cam b21 on said shaft as a shoulder b2,with which at times eoaots a stop-lever b1, mounted on a stud 39,Carried by a project-ing arm D of the vframework D, the stop-lever whenin the osition Fig. 7 arresting the rotation of the shaft D7 andretaining the weft-selecting nippers in closed position, holding a wefta', as re resented in Figs. 4 and 7. The nippers re erred to andformingpart of the short-weftselecting means are and may be substi'tntiallysuch as represented in United States Patent to Lindsley, No. 119,278,dated Se temher 26, 1871; but the parts ooacting't erewith and hereinillustrated are designed somewhat diilerently.

The head l)wl of the frame D has ears t, that receive loosely a rod bl"of a stop-levermoving device, comprising besides said rod a two-armedplate b, (shown best in Figs. 4, 7, and 8,) the lower depending arm ofwhich has a foot b, ad'ustably connected thereto he rod b has at itsupper end a nut b", that limits the descent of said rod, and below itsupper bearing said rod has a connected nut bl, against which bears theupper end of a s )ring bl?. This spring (shown in Figs. 4, 7, an 8, butomitted from Fig. 1,)

is used chiefly as a eounterbalanee to overcome the weight of said rodand its attached parts and to aid somewhat in moving the stop-lever bfrom the position Fig. S into the osition Fig. 7. The hub of the stolever lill* surrounds loosely the stud 39, ani between the hub of saidlever and the head 4() of said stud there is interposed a spiral spring40, that normally acts to hold said lever in the position Fig. 4. Thestop-lever has a depending outturned portion 42, rovided with aroller-stud 41. The end of t ie longer arm of the lever t is slotted toembrace a pin b, extended upwardly from the arm 12.

The stationary member D of the nippers has a projection provided with agroove leaving side walls 13, between whiohis mounted a slide-plate14,havin 1u s 15, that receive and constitute bearings or t e journals of ashaft 14X, Jfrom which projects a short-weft feeler 16. The upper end ofthe shaft 14X is surrounded by a spring 17, that acts normally to movethe feeler into weft-feelingposition, said feeler when moved by saidspring traversing the position that should be occupied byV the shortweft if engaged by the nip ers, and in case a short weft is absent theleeler is arrested by the lower end of the plate 14 after, however,passing the lower end of the stationary member D. The plate 14 isslotted, as shown, to receive a pin projected from the nipper member D',to which pin is connected the lower end of a spiral sprin 19, the upperend oil which is connected wit an extension of said plate, said springacting normally to move said late downwardly in-said guideway until tsupper end of the slot in said plate meets said pin, as shown in Fig. 7.The shaft of the feeler 14x (see Figs. 4, 7, and S) has a prijection 18and a downturned linger 20, said nger when the rod D1 occupies itslowest position meeting an incline 21 (see Figs. 4 and S) on the top ofthe shuttle-box, said incline acting on said `linger to turn the rod 14and move the feeier 16 away from the lower end of plate 14 and outwardlywith relation to the portion D of the nippers.

The stop-earn lil on shaft D7 has a shoulder el, (see Fig. 7,) that isengaged by the stop-lever, as shown, when tie nipper is raised and aholds a short weft, the arm 12 of the two-armed )late l?" at such timemoving said stop-lever irom the position Fig. S into the position Fig.7. The arm 12 turns the stop-lever to arrest further movement oi theshal t D1 only after the nippers have selected a short weft and holds itin position to be acted u on by the feeler preparatory to being engage(by the short-weft holder. ln the descent of the rod D to put the nip)ers in contact with the bunch of short weite the lower end of the slide14 meets a projection 14X, connected, as shown, with the shuttlebinder16", ivoted at 162, and lsaid slide is arrested whi e the rod Dcontinues to de- IOC IOS

scend, as in Fig. 8, and at this time the feeler 1G is turned backwardlyby the incline 21 far enough against the sprin r 17 to permit the shortweft, il" selected7 tothe put in the path of movement of said fceler`Fig. 8 shows the nippers open and in position to be closed by the springl() when the ni per-opener D* is permitted to move to the let in saidfigure by its spring 20X, the cam D being of such shape as to permitsuch movement. Vhen the nippers are closed, the rod Dl" is immediatelylifted and the projection 2() of the feeler-shaft retires from theincline 21, letting sprin f 17 turn the feeler into feelin position,andi thenippers have selected a slziort weft and hold the sameinthe athof movement of the weft-holder the fee er will meet the said short weftand the stop-lever Will be turned to engage the stop-cam if". As the rodD1" is completing its upward movement after a short weft has beenselected by the nip ers the end of the rojection 18 of the fee er-shaft,the fecler liaving met a selected short weft, is retained in suchposition that it meets the foot b and lifts the rod b1", causing the arm12 thereof to turn the stop-lever fiom the position Fig. Sinto theposition Fig. 7, thus stopping temporarilyv the further rotation of theshaft D7 of the short-weft-selecting means, and consequently thereciprocation of the rod D1 and nippers is stopped until at such time asthe said rod and ni pers in the cycle of operation of thc loom sliouldagain descend to select another short weft, when said stop-lever ismoved, as will be described hereinafter, to release the stop-cam b21 andlet the shaft D7 be again rotated. Should, however, the nip ers fail tocatch a short weft, the feeler 16, when turned by spring 17 as the rodD" is raised after an unsuccessful attempt to seize a short weft, willbe arrested by the plate 14, which will leave the end of the projection18 in such position with relation to the finger 15 of the two-armedlever b that when the rod Dl and nippers rise the projection will notengage the lower end of the foot b, and consequently the stop-lever willnot be turned into position to stop temporarily the rotation of theshaft D7 and suspend the operation of the short-Weft-selecting means. Inthis way it will be understood that the nippers have one or more chancesto engage a weft.

The action of the short -Weft selecting means takes place in a definedportion of the cycle of operation of the loom, and at a predeterminedtime With relation to the rotation of the crank-shaft, and if it shouldso ha en that the ni pers fail alto ether to et hdl of a short We t inthe erio of time a lotted for that action then o course other means thanthe stop-rod-moving means so far described must be rovided forautomatically moving the stopever from the position Fig. 8 into theposition Fig. 7 to stopthe shaft D7 and hold up the nippel's in theposition Fig. 7 until such time as the weft-selecting means should beagain moved to select a short weft, the holding up of said nipperspreventing injury to the same by the return of a shuttle into its box.lf the short-weft-selecting means fails to select and present a shortweft, inipcrfect goods would of course be woven, and consequently forthe production of perfect goods it is essential that the continuedmovement of the shed-forming and shuttleboX-moving parts of the loommust depend upon the fact that the short-weft-selecting means has,within the time allotted for its operation, selected a weft. So, also,it will be understood that in case a short weft should not be selectedby the nippers of the short- Weft-selecting means Within the timeallotted in each c Ycle of operation of the loom that the sto ever b1must be moved independently o the rod b1 and its attached )arts thatsaid lever may be put into the position shown in Fig. 7 until theweft-selecting means is again to be started into operation. It will alsobe understood that the shaft D7 is held temporarily at rest with the nipers of the selecting mechanism holding a siiort weft, as in Fig. 7,until that weft has been deposited properly in the shed and thatthereafter in the proper position in the cycle of operation of the loomthe sto -lever bl" must be moved to release the cam 7 and ermit theshaft D7 to be again rotated that t ie nippers may select another shortweft.

The means for moving the stop-lever b1 outside of the rod b and itsconnected arts, before referred to, Will now be described), and it willbe understood that the means to be described for this purpose isduplicated at both ends of the loom, so l need herein describespecifically the parts at but one end of the loom.

The loom end (see Fig. 2) has a stud 47X, on which is mounted agear-wheel 47, that derives its motion of rotation from a gear 48, (seeFig. 1,) fast on the cam-shaft, said ear rotating twice While rotatingthe Whee 47 once. The wheel 47 has an attached cam 50, that in itsrotation meets the foot 6() of a sliderod 45, on the front end of whichis connected an arm 44. The slide-rod, surrounded by a spring 62 andhaving a fixed collar 61, is sustained in bearings of a frame 46,connected by screws 46 to the end oi' the loom. The spring 62 actsnormally to keep said foot in the path of movement of the cam 50, thelever 44 when the foot is out of contact with said cam being out ofcontact with the rollerstud 41. The cams 50 on the Wheels 47 at oppositeends of the loom are so located one with relation to the other that theaction of j each cam is timed to the requirements of the loom and to theoperation of the short-weftselecting means at opposite ends of the loomand to the movement of the short-weft shut- IOO tle. If in the operationof the short-weft-selecting means the nippers fail to select the shortweft in the allotted time with relation to the cycle of operation of theloom, it will be understood that the rod b" will not be lifted, and theshaft D7 and short-weft-selecting means would continue to operate andthe movements would be of no use whatever, so the stop-lever b mustbemoved at times from the position Fig. 8 into the position Fig. 7 byother means. When the nippers stand in the position Fig. 7, the foot t,carried by said rod, occupies its highest. position and the extended arm12 holds the stop-lever Z219, as shown in said figure, thus temporarilyarresting the action of thc Welt-selecting means.

In this situation inthe continued movement of other parts of the loomthe rotating cam 50, carried by the wheel 47, acts upon the foot of theslife-rod 45 at exactly the proper pre1`etermined time in the cycle of oerations of the loom and moves outwardlDy the arm 44, fast on said rod,said arm con tacting with the roller-stud 41, shown as carried by saidstop-lever, thus sliding the hub of said lever on the pin 39 inopposition to the spring 40, this movement being for a distancesufficient to remove the upper end of said stop-lever from engagementWith the projection at the face of the cam b21, thus permitting theselecting means to be again started. As the cam 50 leaves the foot 6Uspring 40 acts to move the stop-lever inwardly on the stud 39 toward thecam b2x into the position Figs. 4 and 8, From the position Fig. 8 saidstoplever may be moved into the position Fig. 7 by the following means.'If, for instance, the nippers have selected a weft, the stop-lever b1?is put in the position Fig. 7 by the arm 112, before described, as itrises with the rod blo, and as soon as the projection of cam b21 meetsthe end of stop-lever the selecting means is again temporarily arrested.If the selector fails to get a weft, the lay in its re ular backwardstroke causes the long arm o said stoplever to be acted upon by the arm44, extended from the rod 45, and turns said stop-lever about its stud39 in a direction to put the upper end of said stop-lever in suchposition that it will meet the cam b, and as soon as the projection b2of said cam meets the end of said stopdever further rotation of theshaft Dl, actuating the weftselecting means, is stopped until such timeas the short-weftse lee-ting means can be again permitted to act. Whenthe shaft D7 has been stopped, as dcscribed,to suspend the operation ofthe weftselecting means after said means has failed to select a weft,the weft-selecting means must be again started in operation at a periodwhen in the movement of the crank-shaft in the cycle of operation of theloom the time again arrives when the weft-selecting moans should againoperate. The weft-selecting means can he started only by the action ofthc cam 50 on the foot 670 of rod 45, as above described.

Sfiort-/weftwontrolling means-w-To prevent any possibility of the shortwefts left by the shuttle during its movement through the shed curlingup or getting into such a position that when the reed meets the shortweft to beat it into the shed said weft might be bent or looped, I haveprovided short-weftcontrolling means that will act to retain said weftin the position in which it leaves the shuttle and hold the short weftuntil the reed meets and beats the same into the fell. This invention isnot limited to the exact means shown for acting against and controllingthe position of said short weft and rcventing it curling in the shed;but I have erein chosen to illustrate for this purpose some or all ofthe warps, said Warps being made to grasp the short weft by apreliminary partial closing of the Warps onto the short weft immediatelyafter or While the shuttle is laying said short weft in the shed andbefore closing and crossing the Warps for a succeeding shed. The meansfor controlling the position of the short Wefts by a preliminary closingof the warps, as stated, is shown in Figs. 11 and l2. The cam-shaft Ahas a cam G, that acts upon alroll G' of a forked leg G2, jointed at G3to one end of an elboivdever G, pivoted at G5. One arm of thiselbow-lever has pivoted upon it at Gr a rod Gi, the upper end of whichis adjustably connected. with one arm of a lever G8, pivoted at G andforked at its opposite end to embrace a stud G10, extended from a hollowtube G, adapted to he slid in suitable guideways G13, there being liketubes and guideways at the opposite ends of the loom. The hollow tubes(l12 at their lower ends at opposite ends of the loom have connectedwith them in suitable manner-21s, for instance, by set-screws-across-rod G15, having, as shown, one or more connected fin ers Gm,notched, it maybe, at its lower en -to embrace one or more Warps. Thelever G8 has a stud d, that is connected by a link d with a stud d of alever d, slotted at its ends (see Fig. 11) to embrace a stud d4,extended laterally from a head d5, connected with the upper end of a rodd, that in practice, as herein shown, is extended through the hollow rodG12, said rod d5 having suitably secured to it near its lower end across-bar d", having one or more slotted lingers da, like the fingersGm. As shown7 the fingers d* and G1 stand one in front of the other, andthe prongs of the iingers at all times embrace some of the warpthreads,and when the ngers are separated to their farthest extent the slotsbetween one and the next finger are of sufficient length to permit theshed to he fully opened by the shed-forming means, and when the 'lingersare closed, as shown in Figs. l l and 12, then those Warps embraced bythe fingers are IOO IIO

brought together or have given to them a preliminary closing movement,so that they may act, as has been outlined, upon a short weft laid orbeing laid in the shed. Fig. 1.1 shows some of the harness-frames withusual lieddles having warp eyes to receive the warp-threads. Theseharness frames or heddles will and may be operated, as has been stated,in any usual. manner according to the class of weaving to be done. Thewarps that are moved independently of the shed-forming n'iechanism to inthis instance of my invention control the position of the short weftsand. prevent them from curling are sustained by the whip-roll B, ithaving a slotted arm. e, that is connected by link e with the lever G4,before referred to. Other warpthreads taken from the beam B are extendedover the usual roller-rest The link and arm constitute part of an easingmotion that )erinits slack in the warp-threads that are to be partiallyclosed on and to prevent the short weft from curling up. In Fig. 11 thef ull linesf in front of the reed represent the warps with the shedfully open, the shuttle shown by dotted lines in said figure beingsupposed to be moved through the shed while the lay is at its backcenter, as in said figure, and during this inovementof the shuttlecontaining the short weft, one end of the weft being retained by theweft-holder,` the short weft is laid in the shed by the movement of theshort-weft shuttle through the shed, and supposing that the leading endof the short-weft shuttle has arrived substantially at its box at theopposite end of the loom and is about to give up the short weft thenbeing laid by it, then at this time the controlling means eoaeting withsaid short weft acts to prevent any curling or wrong position thereofwith relation to the length of the warps. At this time the cam G movesthe hollow tubes Gr12 and the rods d into the position Fig. 11 andimmediately causes those warps, under the influence of the fingers G16d8, to be moved toward each other, rep-l resented by the inner threadsmarkedf 1n Fig. 11, and at the same time the whip-roll B is permitted todescend to afford the necessary amount of slack to permit of suchmovement of the threads f before the final action of the harnesses inchanging the shed to inclose the short weft just laid therein, the warpsso partially moved closing the shed sufficiently to enable saidwarp-threads to act as weft-controllers and keep the short weftsubstantially straight to be acted u on by the reed and be carriedforward to the ell.

In myinvention as herein illustrated Ihave represented but a portion ofthewarps as used to control the short weft to prevent it from curling orwetting out of place; but it will be understood that all of the warpsmight be so closed, if desired, by contact therewith of any suitablemeans without departing from my inventionf-as, for instance, by the rodsG15 and d1, the fingers G1 and d being wholly omitted, and these rodsniight be used by simply changing the shape of the cam G.

b'Lcd-nm'ing means- The cani-shaft (see Fig. 3) has a cam H, providedwith a groove that receives a roller-stud ll', mounted on a lever lll,connected by rod ll3 with the lever A5 (see Fig. 13,) for moving theknives 14 of the dt)bby-motionJ such as indicated by like number in`United States Patent No. 388,318, said knives engaging at the propertime hooks connected with harness-levers fully shown in said patent andjoined with harness-frames having heddles7 all as provided for in saidpatent.

Fig. 13 shows in position theworm-toothed gears h and h', secured,respectively, to the shafts h2 h3, carrying, respectively, theshedforming pattern chain or cylinder h1 and the shuttle-box patternchain or cylinder h5, each designated by a dotted circle, as the sameare and may be of conventional construction.

The shaft H7, sustained in suitable bearings HS, has worms H l'l toengage and actuate intermittingly said pattern-cylinders, said shafthaving keyed to it near its inner end a clutch-hub H9, having an annulargroove to receive a fork H1, which constitutes a clutch- Inover. Theclutch-hub H9 has a hele at its side next the toothed ear H12, which ismounted loosely on sha Yt H7 and provided with a ping (see Figs. 15 and16) to enter a hole in the hub H9 whenever said pin registers with saidhole. The gear H12 is supposed to be driven constantly through a trainof gearing (shown in Figs. 3 and 13) from a gear H20 on the crank-shaft,the rotation of the gear H12 being in unison with the motion of thecrank-shaft. The fork H10 referred to is located at the end of an armg,fast on an upright shaft g2, suitably sustained in bearings 62 at theleoni end the lower end of said shaft having a second arm g1, that isextended forwardly to a point, as shown, under the breastbeam,|where itis provided with a stud g4. A spring h1, surrounding shaft g1, actsnormally to cause the lever g' to move the hub H9 into its clutchingposition, Figs. 13 and 16. The stud g4 is adapted to be acted upon by aside cam g5, secured to a rock-shaft g, usually employed to throw theshi per out of its holding-notch and stop the oom; but it will beunderstood herein that said shaft does not releasea shipper and stop theentire loom. The shaft g1 will, however, be rovided with its usualspiral spring to hold t 1e side cam g5 normally in the position Fig. 3.This shaft is herein turned in one direction against said spring by thedagger g?, pivoted at g8 and connected by link g with an arm g1,carrying a feeler 912, commonly used in connection with the usual weftsto -motion of the lay, said arm, when to turn sai shaft, being liftedinto the dotted-line position, Fig. 3, the feeler at such lOO time,owing to the absence of either the short weft or the continuous weft,having dropped into the dotted-line position, Fig. 3. When the daggermoves the rock-shaft g, the cam g5 moves the lever g to slide theclutch-hub H longitudinally of the shaft from the position Figs. 13 and16 into the position Fig. 15 in the absence of weft, immediately freeingthe shaft H7 from the control of gear H, leaving said shaft and bothpatterncylinders at rest. The disconnection of the clutch-hub H from theear H12 is effected just before the pattern-cy inder is to be started toeffect achan cof pattern. Thestopping of the pattern-cy inders does not,however, stop the weft-selecting means, and the latter may continue tooperate until stopped b f the lever h1", as before described, and the sort- Weft shuttle in the meantime continues to move into position thatthe weft-selectors may engage a short weft, the movement being continueduntil a short weft has been selected. A weft having been selected andinsorted, the feeler working with the lay will be held up, andimmediately the attern-surface will be started, and this wit out amispick. It will be understood when the pattern-surfaces are stopped,due to the absence of weft, that the knives 14 continue to hold open thesame shed until suoli time as the short weft has been properl laid inthe shed g also that the da ger g?, wliich engages and moves the rock-sraft g6 throu h intermediate connectors, moves the clutch or pin whichstops the pattern-surfacesJ just before a new weft is to be presented,to change the shed, and the knives 14 remain at rest until the pin againenters the clutchJ whichwill occur when the selecte-d weft is insertedin the shed. This done,the feeler engages said weft and permits thedagger g7 to pass under the rock-shaft g. The action of spring h1 Willcause the pin g to enter when it registers with the hole in the hub H",and the pattern-surface will then be started immediately at the sameplace in its cycle of operation of the loom at which it was Withdrawn,and at the same time the shuttle-box pattern-surface will be started.

In the operation of the loom as the lay is going toward its frontposition to beat u the weft if a short weft is not in the she( thefeeler gl2 will fall into the dotted-line position before the cam Hoperates the knives for moving the usual harness-levers and also beforethe shed -forming attern cylinder is turned to bring a new indicator inposition to change the shed. When the dagger g" strikes the projectiongs* (see Fig. 13) of rock-shaft g, the shaft g2 is turned and moves theclutch-hub H" to disengage the same from the driving-gear H, thus stopinthe pattern-surface. The lay now is on its ont center and starts to makeone more revolution. The selector, as has been stated, repeats itsoperation in the time allotted in each cycle of operation of the loomuntil a short weft has been selected and is laid in the shed to sustainthe feeler g, and the knives of the shed-forming mechanism are operatedand remain in engagement with the same hooked jacks, thus obviatinchanging the shed, this being made possible owing to the fact that theindicators of the arrested pattern-surfaces continue to act on the samehooked jacks, If a short weft is roperly selected Within the prescribed'al otted time and laid in the shed, the da ger will pass under the.projection g6X of tie rock-shaft y Without turning the same, andimmediately the spring h1 acts and allows the pin g to enter the hole inthe hub Hg, starting the shaft H7 and its Worm to turn and move thepattern-cylinder, the latter being started before the cam H starts themovement of either knife-bar from its extreme inward toward its extremeoutward position.

The shaft H7 is employed to actuate both the shed-formingpattern-surface and the shuttle-box pattern-surface. Each patternsurfacewill have usual indicators and a worm-toothed gear.

The arm g3 has connected with it a chain h, carried over a sheave h andconnected with the aWl h", em loyed for moving the ratchettoot ied gearli; for moving the take-u k. The movement of arm g3, as descried throughsaid chain lifts said pavvl from the teeth of said ratchet-toothed gearand stops further movement of the take-up.

In practice the crank-shaft will have applied to it usual fast and looseor a clutch pulley to control the movement of said shaft and the othershaft of the loom driven therefrom. 1f the supply ci' weft is exhausted,the crank-shaft must be stopped, and this may be done by the operator orin any usual manner.
